Fellowship; friendly communication or participation; a state of giving, receiving, and agreement. Also, the partaking of wine and bread together, in Christ's name, in rememberance of Him; also called, 'sacrament of the eucharist'; the 'celebration of the Lord's Supper' or 'the Lord's Table'; or, the 'Blessed Sacrament.'

Be ye not unequally yoked together with unbelievers: for what fellowship hath righteousness with unrighteousness? and what communion hath light with darkness?
2 Corinthians 6:14
